Now that I think about it I have some old rough tread 8-19.5 tires on the wheels that go on my 52 1 ton when I get to it.
three look alike and the one i can see without moving the rest says "dual bite HD" or something like that. Another one is a B.F.Goodrich with an almost identical tread pattern.
I had planned to run them on my 1 ton until I needed to buy new tires. If you're interested I could take some pictures, and if you like them I'd need some good usable 8R-19.5 tires as trade and to make it worth my efforts to dismount these and deal with the whole thing. Ideally I'd be looking for a pair of G171's and some normal street tires for the front.
